Bitcoin ETF outflows cross record $4 billion in June

Bitcoin ETF outflows cross record $4 billion in June
Investor withdrew from spot bitcoin funds at their fastest pace ever this month, eclipsing last year's worst period and raising questions about the durability of institutional demand.
JUN 29, 2026

For crypto investors who've held on through the month of June, it's all over but the crying – at least, if the data on bitcoin ETF flows is anything to go by.

US-listed spot bitcoin ETFs posted approximately $4.06 billion in net outflows in June, according to data from SoSoValue — the largest monthly withdrawal since the funds began trading in January 2024.

The surge in exits so far this month is also 14% larger than the previous record of $3.56 billion set in February last year.

The milestone marks a brutal stretch for a product category that was once celebrated as a permanent structural shift in how capital reaches the crypto market.

A streak no one wanted

The deterioration began to take root in mid-May, as bitcoin ETFs suffered 13 straight days of net outflows from May 15 through June 3. That's the longest such streak since the funds launched, according to SoSoValue data cited by Crypto Briefing. Investors pulled roughly $4.4 billion from the funds during that period alone.

The plunge has only continued from there. For the week ending June 6, net outflows reached $1.72 billion, the largest single-week figure since February 2025, according to CryptoPotato reporting on SoSoValue data. Over the four weeks preceding that reading, cumulative withdrawals totaled $5.4 billion. Stretch the window to six weeks, and the number climbs to $5.94 billion.

Even as the week-over-week pace of bleeding briefly moderated – dropping to $316 million and $227 million in the second and third weeks of June – investors resumed their heavy selling in the final days of the month, pulling $1.79 billion in the week ending June 26.

BlackRock's flagship fund at the center of the storm

No corner of the market was spared, but BlackRock's iShares Bitcoin Trust (IBIT) – the largest spot bitcoin ETF by assets – absorbed an outsized share of the damage. The fund reportedly saw approximately $860 million exit in a single reported week.

IBIT's position at the top of the market – supported in part by its inclusion in advisors' model portfolios – has made it both the primary vehicle for institutional entry and a reliable barometer for institutional exit. When advisors and their clients reduce bitcoin exposure, they predominantly do it through IBIT, which holds roughly 60% of the group's total assets, according to at least one past read of Bloomberg data.

Based on the best estimates as of June 26, IBIT held almost $45 billion in assets while holding nearly $743,000 bitcoin, making Fidelity's Wise Origin Bitcoin Fund a distant second with $13.5 billion.

During the selloff in late May, crypto news outlet CoinDesk reported one whale-sized exit from BlackRock's bitcoin ETF, which resulted in $1.29 billion worth of shares being jettisoned in a single trade on May 27.

What is driving the selling

Bitcoin's price has been a central factor. The asset class has slid to a multi-year low of $58,000, with the price hovering in a $58,000 to $60,000 range throughout much of June. The combined assets under management across all US spot bitcoin ETFs have fallen from approximately $104 billion, a decline driven by both the outflows themselves and the shrinking dollar value of remaining bitcoin holdings, according to Crypto Briefing.

The relationship between price and flows has long been self-reinforcing. Modeling by Citi Research, cited by Bloomberg, has determined that for every $1 billion pulled from bitcoin ETFs, prices see a roughly 3.4% drop. The link appears to be working both ways, with outflows amplifying price declines to create a vicious cycle.

Bitcoin itself has been under pressure as it's on pace for its worst monthly showing since the June 2022 serial collapse of several crypto firms, capped off by the implosion of FTX. Against that backdrop, Michael Saylor's digital treasury company Strategy recently dumped $2.5 million worth of its $50 billion hoard of bitcoin holdings.

The June data arrives in a context that would have seemed improbable at the start of the year. The eighth annual Bitwise/VettaFi 2026 Benchmark Survey of Financial Advisor Attitudes Toward Crypto Assets found that crypto allocations by advisors had reached an all-time high, with 42% of advisors reporting the ability to buy crypto directly in client accounts, up from 35% in 2024.

As recently as last December, major institutions including Bank of America were approving advisor-led digital asset allocations for retail clients.
